First time revisitng the game after my first playthrough back in 2011, and it kinda wiped off my rose-tinted glasses that I used to view this game through.
The 2D-stages were a slog to go through. None of them were as good as the classic 2D sonic games. However, the 3D boost stages were as good as sonic gets. Most, if not all, the stages were pretty enjoyable. Each level contained various paths that drastically alter the experience, thus making the process of replaying a level while searching for collectibles more pleasant than I thought it would be.
On the other hand, the side-missions are a quintessential example of boring-filler content. The rival challenges, however, are pretty cool (I find them more enjoyable than the actual bosses).
